24 Claims.

This invention nrelates to fastening `inserting machines .and is illustrated kherein as embodied in a fibre peg linserting machine `adapted :for use in attaching soles toshoe bottoms.

It is present day practice to attach leather outsoles to .shoe bottoms, for example, at their heel seat portions, by libre pegs of the character disclosed in Letters Patent of the United States No. 1,729,169, granted Sept. 24, 1929., on lan application filed vin my name. Such .pegs are driven Without .diiiiculty into leather `soles by .a `machine provided lwith work penetrating awls. rBhe pegging of rubber soles is not, ,however, vaccomplished so readily .since the awllholes close .up when the awl is withdrawn .and there is :danger of crippling the peg,.fparticularly if it is presented even very slightly out of line with Ithe hole.

It is accordingly an object of the 'present .in-

` venticn lto provide an improved fastening inserting machine well adapted for use in attaching rubber soles to shoes. I have found that `the crippling of .the pegs can be prevented in rubber solo work if the pegs aresupported ""'I during the inserting operation at Vtl'le point v.of

peg insertion by means which is arranged :also to apply a compressing force to the rubber vnl" the sole in the direction of fastening insertion. By thus supporting the peg the entering endof f. the peg, while permitted to find -t-he 'hole iin the sole made by the -awl, is supported .against deflection even though there vbe some displacement of the rubber of the sole because of a misalignment of the peg and the hole. By placing the rubber under compression I reduce the thickness of the sole at the-place where `a fastening is to be inserted, so that not only is spreading or bending of the upper end of the peg pre vented by the support which is held `lirrnly in engagement with the compressed `portion .of Athe sole but, when the pressure is released the rubber closes about the upper end of the peg-which, by reason of the manner in which the peg has been controlled andsupported, has maintained .substantially its original form.

and also to 'ap-ply a compressing force to the rubber of the sole 'in the direction of theV length ofthe fastening receiving vhole formed therein by the awl. 'Thus during the inserting operation a continuous supportfor the fastenings is provided between the driver of the machine and the vsurface lof the work. Such an organization comprises a feature of my invention. 'In the construction shown, means is accordingly provided, loperative afterV the throat member has completed its movement `toward the driver, to press the throat member downwardly into forceful engagement with the work preparatory to during the fastening inserting operation and then to return the throat member to its uppermost position. As illustrated, this vmeans is yieldingly Vand adjustably connected to the throat member and includes a spring the initial tension of which may be regulated and through which force is transmitted to thrust the throat member downwardly into engagement with the work to compress the rubber of the sole until a resistance is encountered which causes the spring to yield and to permit the throat member to come to rest.

Although the illustrated'm-a-chine will be hereinafter described with special reference to its use v-f-or attaching rubber soles to shoes, it will be readily seen that the invention is not restricted inits application to such use but is capable of being usefully employed for other purposes including the attachment, for exam-ple, of leather solles to shoes in Awl-iich case the throat member maybe'-moved intoengagement with the work to form a continuous passage for the peg, the means for forcibly thrusting the throat member toward the Work being arranged to yield When the throat-member contacts ywith the surface of the r--leather vsole.

With `the above and other objects and features in view, the invention will now be described with reference to the accompanying drawings and will be pointed out in the claims.

cation for Letters Patent of the `United States, Ser. No. 515,047 filed February 11, 1931 inniy name to which reference may be had for `afull disclosure of such parts of the machine as it is unnecessary to illustrate herein.

The illustrated machine is provided with a column carrying a head 12 on which are mounted the fastening inserting instrumentalities of the machine. The column 10 also carries a work support terminating in a last pin 14 (Fig. l) arranged to support a `work pieceV such as a shoe 16 mounted upon a last 18 with its sole in engagement with a presser plate or abutment 22 carried by the head 12 of the machine. lhe shoe may be positioned relatively to the fastening inserting instrumentalities` of the machine by a gage 24 which can` take any suitable form also carried by the head 12 of the machine.

Mounted in suitable bearings carried by the head 12, of the machine is a cam shaft carrying a cam member 32 provided with a series of cam grooves and surfaces arranged to operate the moving parts of the machine. rEhe cam shaft 30 is connected to a pulley 34, driven from any suitable source of powerf by a belt 36 by means of a clutch (not shown) having a dr ingsurface and a breaking surface and operating substantially as disclosed in said Letters Patent of the United States No. 1,030,775 referred to above. rhe machine is provided with a driver bar mounted for reciprocating movement in vertical ways carried by the head l2 of the machine adjacent to the forward end of the shaft 30. Clamped to the lower end of the driver bar 40 is a driver 42. The driver bar 40 is provided with a rack 44 meshing with a gear segment 46 formed upon the end ofthe forwardly extending arm of a bell crank lever 4 8 fulcrumed at 50 to the head 12 of the machine and having a depending arm carrying at its lower end a roll positioned in a cam track 52 formed in the cam member 32.

t The illustrated machine is provided with an awl which serves to form fastening receiving holes in the work piece presented thereto and to feed the work piece toward and past the driver 42, rThe awl 60 is secured to the lower end of an awl barv 62 mounted `for vertical sliding movement in ways formed in an awl bar carrier 64. The awl bar carrier 64-is reciprocated transversely of the machine by a lever 66 fulcrumed to the head 12 of the machine and carrying a roll 'positioned in a cam groove formed in the rear portion of a cam disk 68 securedy to the forward end of the shaft 30. The awl '60 is moved downwardly to form fastening re-.

ceiving holes in the work by mechanism (not Shown) which may be and preferably is of the type disclosed in Letters Patent No. 1,849,253 hereinbefore referred to, which mechanism in- 'cludes means arranged to permit the awl to come and controlling mechanism therefor of the character disclosed in anappli- -rack '78 meshing with a gear segment 80 formed atl the lowerwend of a lever 82 fulcrumed at 84 to the head 12'of the machine and carrying a y.cam roll 86 positioned in a cam groove 88 formed in the cam membeiBZ.

The fibrefastening material 90, from which the pegs inserted by the machine are severed,

is carried by a reel 92 mounted upon a bracket 94 secured to the head 12 of the machine (Fig. 1). In the illustrated machinethe fibre fastening material- 90 is fed through a passage-way 91' .(Fig. 4) the lower end .of 'which is inalinement with'the driver passage of the throat member '70 when the latter is Iin its rear-most positionv by feeding mechanism preferably, though not'. necessarily, of the type disclosed in Letters Patent No. 1,849,253 referred to above and the length of each feeding movement .of the feeding. mechanism is controlled by mechanism of'substantially the Vsame Vconstruction as that shown in vr said Letters Patent so -that fibre pegs will be severed from the fastening material 90 as the. throat member moves forwardly each of a .length determined by the thickness of the work piece at the point where it is .to be inserted. The feeding mechanism includes a feed dogY 100 (Fig. 2) pivoted to a block 102 formed at the end of a tubular member 104 which forms a guide for the fastening material and is mounted for reciprocating movement lengthwise of thestrip of fastening material 90 in a slideway formed in a bracket 106 secured to the head 12 of the machine. The extent of the reciprocation of the block 102 will determine the length of fastening material fed. Accordingly, the machine is .so organized that thereciprccation of the block 102 is controlled by the awl bar 62 and bears. a definite relationv to the distance which the awly isnprojected below the presser plate 22 ofthe machine in each cycle of operation.A Accordingly, the block 1021s pivoted to a block-103 mounted in slidways formed at the forward `end of a lever 110 `fulcrumed at 112 to the head 12 of the machine andhavinga rearwardly and forwardly extending arm pivoted at 114 to the forward end of the link 116. The linkl 116 is pivoted intermediate between its ends to the forward end of another link 118 the rear end of which is adjustably pivoted by a bolt and slot connection 120 to a lever'122nfulcrumed at 124 to the head 12 of themachine Aand provided with a rearwardly extending `armv carryingqa. roll positioned in a camtrack -126 -formed in thewcam member 3.2. As illustrated the lever 122 is'effective also to transmit-they pressure relieving movement to the work support 14 which facilitates the feeding of the work, that movement being vtransmitted through va rod 128 to mechanism of the character Afully shownv and described in application Serial No:l 515,047`hereinbefore mentioned. The rear lend of the link 116 is provided with a slide member positioned in aniarcuate slot 130 formed in the upwardly and rearwardly extending armv of a lever 132 fulcrumed at 134 to the headk 12 of the machine and having a forwardly extending arm provided with'a gear segment 136 meshing with a gear segment 13S formed upon the rearwardly extending .arm of a lever 146 ulcrumed at 142 tothe head 12 of the machine and having a forwardly extending arm lill provided with a gear segment (not shown) meshing with a rack'formed upon the rear surface of. the awl bar 62. ri"hus it will be that the lever 132 will be rocked through an angle which is determined by the extent of the reciprocation of the awl bar 62. The slot 130 has a radius of curvature equal to the effectivelength oi the link 116 and the lever 132 is so positioned that the slot 130` is concentric with the pivot 114 between the lever 110 and the lever 116` when the parts are in the position which they occupy when the entering end of the awl is ush with the lower surface of the presser plate 22. As awl 60 descends below this position the lever 132 is rocked in a counter-clockwise direction, as viewed in Fig. 1,-the extent of this rocking movement depending upon the distance which the awl moves before it is stopped by impact with the metal bottom plate 19 of the last 18. r'hus the rocking movement of the lever 122, which is uniform in each cycle oi operation of the machine, is varied as it is transmitted to the lever 11G, the extent of the rocking movement of the lever 110 increasing with the increased eccentricity of the slot 130 relatively to the pivot 114 caused by an increased worl; penetrating movement of the awl 60. The bolt and slot adjustment 120 between the lever 122 and the link 118 permits the length of the fastening mate i l fed to be increased a greater or less amount over the thickness of the work piece penetrated by the awl 66.

- The lever 72 is yieldingly and adjustably connested at its forward end to a lever 150 pivoted at 152 to the head ,12 of the machine and having a laterally extending .arm carrying a roll 154 positioned in a cam groove 156 formed in the iront portion of the cam plate 68. Connected to the forward end of the .lever '72 byv a ball and socket joint is an upwardly extending threaded rod 15S surrounded by a compression spring 166 bearing at its lower end against one of a pair of adjusting nuts 162 mounted on the rod 158 and at its upper end against a shoulder formed on a nipple 1611. The nipple 16e is provided with a globular end retained in a hollow seat formed in the forward end of an arm 166 of the lever 150 and has a central aperture through which passes the reduced end portion of the rod 158 on the upper end oi which is mounted a washer 176 and a pair of adjusting nuts 172.

In the operation of the machine a last v18 upon which the shoe 16 is mounted is placed on the last pin 14 of the work support. The work support is then moved'upwardly to clamp theshoe 16 yieldingly against the presser plate 22, the shoe being positioned by the gage Y24 in the manner usual for performing they heel seat nailing operation after which the work support is locked in said position against downward movement during operation of the fastening inserting instrumentalities by mechanism of the type disclosed in application Serial No. 515,047 .hereinbefore referred to. When the machine is started the awl 60 is thrust downwardly into the sole until its lower end comes substantially into contact with the metal bottom plate 19 of the last 18 (Fig. 1). The awl is then moved `transversely to the left (as viewed in Fig. 2) ieeding the Work piece and bringing the awl into the line of drive. The awl is then withdrawn and returned to the position which it occupied at the beginning of the cycle of operation. The Work penetrating movement of the awi which has just been described is effective through the Colmsction `between the awi bar 62 and the lever 132 to rock the lever 132 in a counter-clockwise direction, as viewed in Fig. 1, to a position which is determined by the thickness of the shoe bottom, as measured by the movement of the awl, thus controlling the angular relation between the link 116 on the one hand `and the lever 132 and the link 118 on the other so that the rocking movement of the lever 140 rocks the lever 110 to an extent suhicient to cause the latter to move the block 102 through a path which causes theV feed dog and a surface formed on the block 162 f with which the dog 166 cooperates to move through a path suiicient to feed the fastening material a distance equal to or if desired slightly more `than the thickness of the shoe bottom parts which the awl 66 penetrates.

The fibre fastening material 90 is then severed by the forward movement of the .throat member 70 and is brought forward into line with the driver Ll2 after which the cam 156 rocks the lever 150 in a counter-clockwise direction as viewed in Fig. 2 compressing the spring 166 and .forcibly thrusting the throat member '70 downwardly into engagement with the sole to compress the rubber of the sole in the direction of the fastening receiving hole formed therein by the awl 60 (Fig. 1). it Vthis time a dwell is preferably provided in the movement of the lever 150 while the driver 42 descends' to drive the fastening into the hole formed in the work after which the cam 156 rocks the lever 150 in a clockwise direction to return the throat member '76 positively to its uppermost position. Y

. Since the initial tension ci the spring 166 may be adjusted by movement of the nuts 162 it will be readily seen that the force transmitted to the throat member 70 through the spring 166 may be varied so that the throat member 70 will be pressed with more or less force against the surface of the sole. I have found in operating upon rubber soles that by increasing the tension of the spring 160 sulciently to cause a substantial compressing force to be applied to the sole not only is the entering end or" the -peg more firmly supported against crippling but since the thiol;- ness of the compressed portion of the sole is less than thelength of the nbre peg, as measured by the work penetrating movement of the awl, the upper end of the peg is supported against spreading at the end of the fastening inserting stroke of the driver by the walls of the driver passage in the throat member. Thus when the pressure on the sole is released by the return or the throat member 70 to its uppermost position the rubber of the sole closes about the upper end of the peg which hasretainedits original form. r
